The NASA and contractor engineers who have been crawling over the External Tank (ET) for the shuttle Discovery have good and bad news. Good: The cracks that postponed the shuttle's launch have been fixed and the area strengthened. Bad news: there are four new cracks (or previously undiscovered ones) on the other side of the tank. The latest (February 3) launch date may or may not be practical. What is unnerving is that they're not sure of the root cause of the cracks. Fingers crossed guys, and MAKE SURE it's good to go.
